Answer:
<u>f(x)=x²-2x-2</u>
Step-by-step explanation:
<em><u>f(x)=ax²+bx+c</u></em>
f(0)=-2 => c= -2
f(1)= -3=> a+b-2=-3; a+b=-1
f(2)= -2; 4a+2b-2=-2; 4a+2b=0; 2a+b=0
a+b=-1 and 2a+b=0
2a+b-(a+b)=0+1=> a=1
2+b=0=> b=-2
f(x)=x²-2x-2
Answer:

Step-by-step explanation:
Given:
The area 'A' of a circle with radius equal to 'r' is given as:

In order to rewrite the given formula in terms of radius 'r', we need to isolate 'r'.
Dividing both sides by π, we get:

As
, the above equation becomes:

Taking square root both the sides, we get:

We neglect the negative result while taking square root as the radius can't be a negative number.
Thus, the formula for radius 'r' in terms of area 'A' is given as:

Answer:
<h2>The answer is 1</h2>
Step-by-step explanation:
First of all transform the expression using trigonometric identities
That's



So we have

Reduce the expression with tan x
We have

Reduce the expression with cos x
That's

Reduce the expression with sin x
We have

We have the final answer as
<h3>1</h3>
